Dale Berquist is the husband of the murder victim Barb Berquist. He is shocked when he hears that his wife, Barb, is dead. After Booth notes that coupons were found in her clothes, Dale takes him to the basement and shows him Barb's inventory. The entire basement is filled with food purchased with coupons. Barb was an extreme coupon collector, so she was always on the go. The last time Dale saw Barb was when she went to the Fields Market in Frederick. Later, he admits that he cheated on his wife. He'd had enough of Barb's obsession with couponing; she was more interested in coupons than him. Dale admits to Booth that he wanted to come clean to Barb about his affairs, but Booth did not really believe him.
